Ford 351 Windsor Intake Manifold Torque Specs
Ford 351 Windsor Intake Manifold Torque Specs with application boundaries, staged installation guidance.
For the covered 1993 F-150 5.8L/351 Windsor, tighten the intake-manifold-to-head bolts in the factory sequence to 23–25 lb-ft (32–33 N·m).
For the covered 1993 F-150 5.8L/351 Windsor, tighten the intake-manifold-to-head bolts in the factory sequence to 23–25 lb-ft (32–33 N·m).
The exact value is tied to the documented 1993 truck 351W production manifold. It does not cover 351 Cleveland, 351M/400, a 302 intake, or aftermarket aluminum combinations.
Dry-fit the correct-width 351W manifold, confirm port and coolant-passage alignment, and follow the gasket/sealer instructions before applying the numbered Ford sequence.

Ford 351 Windsor Intake Manifold Torque Specs
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Manifold-to-head final | 23–25 lb-ft | 32–33 N·m; Ford sequence |
| Lower EFI intake to head | 22–32 lb-ft | 30–43 N·m in covered data |
| Upper-to-lower intake | 12–18 lb-ft | 16–24 N·m; separate group |
| Aftermarket aluminum | Manufacturer chart | Material and gasket dependent |
Dry-fit the correct-width 351W manifold, confirm port and coolant-passage alignment, and follow the gasket/sealer instructions before applying the numbered Ford sequence.
How to use this specification correctly
- 01
Identify the engine code, model year, casting, gasket and exact fastener kit before disassembly.
- 02
Clean and inspect threads, bolt holes and mating faces using the component manufacturer's limits.
- 03
Follow the exact staged pattern with the specified lubricant or sealant; record torque and angle completion.
The 1993 truck 351W application
Ford specifies 23–25 lb-ft for the manifold-to-head fasteners in its numbered pattern. EFI upper/lower fasteners are separate groups, so identify exactly which joint is being assembled before setting the wrench.
A 351W intake is wider than a 289/302 intake because of the taller deck. Correct torque cannot seal a mismatched manifold or compensate for port and coolant-passage misalignment.
Assembly details that control sealing
Dry-fit first, then apply the gasket maker's approved sealer only at the required coolant and end-rail locations. Lower the intake squarely so the seals do not shift.
Use gradual passes through the factory sequence. If aluminum heads, an aftermarket intake or a nonstandard gasket is present, use the matched component instructions and surface-finish requirements.
Why 1993 F-150 5.8L/351W V8 identification changes the specification
The exact value is tied to the documented 1993 truck 351W production manifold. It does not cover 351 Cleveland, 351M/400, a 302 intake, or aftermarket aluminum combinations.
Dry-fit the correct-width 351W manifold, confirm port and coolant-passage alignment, and follow the gasket/sealer instructions before applying the numbered Ford sequence.
Assembly controls that prevent false torque
- Use the specified thread condition and lubricant.
- Separate main bolts from small or special-position fasteners.
- Use an angle gauge where torque-to-yield stages are specified.
- Stop if a fastener reaches the setting before the joint seats normally.
Ford 1993 F-150 5.8L/351W V8 specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
Ford 351 Windsor Intake Manifold Torque Specs FAQs
What is the 1993 Ford 351W intake-manifold torque?+
The covered F-150 procedure specifies 23–25 lb-ft in the factory sequence.
Will a Ford 302 intake fit a 351W?+
Not as a direct production replacement; the 351W's taller deck creates a wider intake span.
Are upper and lower EFI intake bolts the same torque?+
No. The covered service data lists separate fastener groups and values.
Should an aluminum 351W intake use 25 lb-ft?+
Use the intake and gasket manufacturers' instructions; they may specify another value or sequence.
